Re: [VuFind-Tech] Solr Alphanumeric browsing

Is the issue here that, because the call numbers in the index are getting normalized, they don't match up with range queries that are non-normalized? i.e. the problem is that Solr does not apply normalization to the content of range queries? If that's it, I'm not sure if there's a solution or not - I think there are some more flexible features available now, but I haven't looked into it in any detail yet. Perhaps when I get around to working on VUFIND-172, that will reveal some relevant tools. - Demian From: Osullivan L.

Subject: Re: Solr Alphanumeric browsing Hi Demian, It's related to the patch I submitted a while back. http://vufind.org/jira/browse/VUFIND-598 The normalisation worked fine, as did the sorting but the ranged searches produced inconsistent results. I tried using the solr mailing lists but (I think) they confirmed that solr wasn't capable of doing that at the time.

I don't see why any version of Solr should be incapable of alphanumeric ranged searches - I thought a range query could take any string as each end and would return everything alphabetically between them. If it need to sort things numerically rather than alphabetically, I can see how that could be a challenge... but otherwise it seems like it should work as-is. Do you have an example of what you expect and what you actually get? - Demian From: Osullivan L.

Subject: [VuFind-Tech] Solr Alphanumeric browsing Hi Folks, A while back I look into ranged callnumber searches (normalised callnumbers) with solr. While sorting by the normalised callnumber works fine, I came to the conclusion that the callnumber ranged searches didn't quite work. Does anyone know if the new releases of solr are capable of alphanumeric ranged searches?
